Abstract
Damit ein Abgasendrohr einer Abgasanlage keine zu große Erwärmung erfährt und das umgebende, aus Kunststoff bestehende Heckverkleidungsteil sich nicht verformt, wird dem Abgasendrohr entweder nach dem Venturiprinzip kühle Fremdluft zugeführt oder es wird über ein Luftleitrohr die Fremdluft in den Abgasstrom hineingeblasen.Thus, an exhaust pipe of an exhaust system does not experience too much warming and the surrounding, made of plastic rear trim part is not deformed, the exhaust end pipe either supplied by the Venturi principle cool outside air or it is blown through a Luftleitrohr the foreign air into the exhaust stream.
Description
Die Erfindung bezieht sich auf eine Abgasanlage für einen Kraftfahrzeugmotor nach dem Oberbegriff des Anspruchs 1.The The invention relates to an exhaust system for an automotive engine according to the preamble of claim 1.
Ein Problem bei Abgasendrohren einer Abgasanlage für Kraftfahrzeugmotoren, welche in einer so genannten Pelle, d.h. in einem Heckabschlussteil aus einem Kunststoff angeordnet sind, besteht darin, dass zum einen die Pelle nicht durch Erhitzung des Abgasendrohrs verformt wird und zum anderen soll das Abgasendrohr lagegenau trotz Erwärmung der Abgasanlage positioniert in der Pelle gehalten werden.One Problem with exhaust pipes of an exhaust system for motor vehicle engines, which in a so-called pelle, i. in a rear end part a plastic are arranged, that on the one hand the skin is not deformed by heating the tailpipe and on the other hand, the tailpipe should be accurate in spite of heating the exhaust system be kept positioned in the pelle.
Dieses Problem wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This Problem is solved by the features of claim 1. Further advantageous features include the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, dass das Abgasendrohr relativ kalt gehalten wird und die Erwärmung nicht die Pelle verformen kann und des weiteren werden durch das Abgasendrohr durch ein stromauf zwischengeschaltetes Wellrohr oder durch einen Wellschlauch Wärmeausdehnungen der Abgasanlage vom Abgasendrohr ferngehalten. Dies wird erreicht, indem das Abgasendrohr einen als Venturirohr mit Fremdluftzuführung ausgebildeten Rohrabschnitt aufweist, an den sich stromauf ein Wellrohr oder ein Wellschlauch anschließt, der mit einem Abgaseingangsrohr der Abgasanlage verbunden ist. Die Fremdluftzuführung kann über ringförmig angeordnete Lufteintrittsöffnungen im Abgasendrohr im Venturibereich erfolgen.The with the invention mainly achieved advantages are that the exhaust pipe end relative kept cold and warming not the pelle can deform and further by the Exhaust tailpipe through an upstream intermediate corrugated pipe or through a corrugated tube thermal expansions the exhaust system kept away from the exhaust pipe. This is achieved in that the exhaust end pipe forms a Venturi tube with external air supply Pipe section has, at the upstream of a corrugated pipe or a Corrugated tube connects, which is connected to an exhaust gas inlet pipe of the exhaust system. The External air supply can be arranged over a ring Air inlet openings take place in the exhaust pipe in Venturi area.
Nach einer weiteren Ausführung kann die Fremdluftzuführung auch über ein eingeführtes Luftleitrohr erfolgen, das mit einer lufterzeugenden Pumpe verbunden ist. Hierdurch wird eine Erwärmung des Abgasendrohres durch Zuführung von kalter Fremdluft vermieden, sei es selbsttätig durch einen Venturieffekt oder zwangsweise durch eingepumpte Fremdluft oder in einer Kombination durch eingepumpte Fremdluft und durch die Luftzuführung nach dem Venturiprinzip.To another embodiment can the external air supply also over an introduced Air duct, which is connected to an air-generating pump is. This will cause heating of the Exhaust tailpipe by feeding avoided by cold outside air, be it automatically by a Venturi effect or forcibly by external air pumped in or in combination by pumped in ambient air and by the air supply to the Venturi principle.
Das Abgasendrohr ist in einem rohrförmigen Aufnahmeelement der Heckverkleidung mit einem Luftspaltraum über Distanzhalter gelagert, wobei zwischen dem Abgasendrohr und dem aufbauseitigen Aufnahmeelement die Lufteintrittsöffnungen in Verbindung mit dem Luftspaltraum stehen. Die Distanzhalter behindern die Luftführung nicht, so dass nach dem Venturiprinzip angesogene kalte Frischluft über die Luftleitöffnungen dem Abgasstrom zuführbar ist und somit dieser eine verminderte Wärme aufweist und das Abgasendrohr nicht so heiß wird, dass das Heckverkleidungsteil verformt wird. Das Abgasendrohr kann aus Materialien, wie Leichtmetall, CFK bestehen. Durch die Zuführung von der Frischluft wird sowohl eine Innenkühlung durch Zumischen von kalter Frischluft als auch eine Außenkühlung durch die Frischluft erzielt.The Exhaust tailpipe is in a tubular receiving element the tail fairing is mounted with an air gap space over spacers, wherein between the exhaust pipe and the body-side receiving element the air inlets in connection with the air gap space. The spacers hinder the air duct not, so according to the venturi principle sucked cold fresh air over the Luftleitöffnungen be fed to the exhaust gas stream is and thus this has a reduced heat and the exhaust pipe does not get so hot that the tail fairing part is deformed. The exhaust tailpipe can made of materials such as light metal, CFK. By the supply of the fresh air is both an internal cooling by mixing cold Fresh air as well as an external cooling through the fresh air is achieved.
Durch die Zwischenschaltung des Wellrohrs oder Wellschlauches zwischen dem Abgasendrohr und dem Abgaseintrittsrohr kann eine Wärmeausdehnung des Abgaseingangsrohres bzw. der Abgasanlage kompensiert werden, so dass das Abgasendrohr keine axiale Verschiebung aus der Pelle bzw. dem Heckverkleidungsteil heraus durchführen kann.By the interposition of the corrugated pipe or corrugated hose between the exhaust gas end pipe and the exhaust gas inlet pipe can be a thermal expansion the exhaust gas inlet pipe or the exhaust system are compensated, so that the exhaust tailpipe no axial displacement from the Pelle or perform the Heckverkleidungsteil out.
Die Lufteintrittsöffnungen werden über eine von einer Pumpe erzeugten Fremdluft mittels eines Luftleitrohres beaufschlagt, das durch das rohrförmige Aufnahmeelement der Heckverkleidung hindurchragt und deren Mündungsöffnung den Lufteintrittsöffnungen von außen zugerichtet ist. Hierdurch wird in vorteilhafter Weise nach der Erfindung eine mittelbare Fremdluftzuführung in den Abgasstrom in Kombination mit dem Venturieffekt erzielt.The Air inlet openings be over an external air generated by a pump by means of a Luftleitrohres acted upon by the tubular receiving element of the rear panel protrudes through and the mouth opening the Air inlet openings from the outside is done. As a result, after the Invention an indirect external air supply into the exhaust stream in Combination with the Venturi effect achieved.
Nach einer weiteren Ausführung der Erfindung ist vorgesehen, dass eine Fremdluftzuführung in das Abgasendrohr ohne Lufteintrittsöffnungen nur über das Luftleitrohr erfolgt, das mit einer lufterzeugenden Pumpe verbunden ist und die Mündungsöffnung des Luftleitrohres stromauf einer Venturiverengung im Abgasendrohr und in der Längsachse des Abgasendrohres angeordnet ist. Hierdurch wird eine unmittelbare Fremdluftzuführung in den Abgasstrom erzielt, wobei durch den Venturieffekt die kalte Fremdluft mit dem Abgasstrom mitgerissen wird.To another embodiment The invention provides that an external air supply in the exhaust tailpipe without air inlets only over the Air duct, which is connected to an air-generating pump is and the mouth of the Luftleitrohres upstream of a Venturiverengung in the exhaust pipe and in the longitudinal axis the exhaust end pipe is arranged. This will be an immediate External air supply achieved in the exhaust gas flow, wherein the venturi effect, the cold external air entrained with the exhaust stream.
